at first a note regarding the preup.sh: this script is directly fetched from the configured repository. In most cases updates.software-univention.de/4 ... l/preup.sh is used. This is the file where I searched for the function yesterday.

From your dpkg-query line I can not see any hints too, but the script is using the "-f" switch to determine the status.example from a 4.0 installation, enhanced for easier reading:

There might be some environmental influence which leads the script to assume that the cyrus-common-2.2 is installed.

In case you are sure that this is not the case (and no other inconsistencies in the package-status are appearing) you could set the mentioned UCRV "update40/ignore_cyrus22" to "true" and skip this check.

That removed cyrus-common-2.4 and all the packages related to it. The system then automtically reinstalled cyrus-common-2.2.
2) I followed the procedure described on See [sdb.univention.de/1213](http://sdb.univention.de/1213)
3) Did an upgrade then to cyrus-common-2.4 and univention-upgrade the passthrough. SOLVED.
Upgrade process is went all good through 4.0 and it is stalled on 4.01 on an error I will post in another thread.
